SHARP Report Summary

Device to measure contrast over 10-12 orders of magnitude

The high dynamic correlator is based on an efficient all reflective attenuation system coupled with high efficiency thin nonlinear frequency conversion BBO crystals to keep ultra-short duration pulses with high intensity at the zero delay.

The system allows to measure a contrast dynamic of 10{12}, covers a temporal range of one nanosecond, which matchs measurements achieved with fast photodiode , and has a temporal resolution of 80fs.
